摘要
从分析影响烘干设备干燥效果的烘干时间、加热温度、运行距离、物料与加热系统的接触面积入手,研制出高湿物料真空连续复合管束烘干设备。干燥主机采用三个不同直径的同心圆筒组成多级干燥室,各个干燥室内设有一定数量的加热管束,利用真空连续干燥、热能按需分配的原理,延长物料在干燥主机内的烘干时间、运行距离,加大物料与加热系统的接触面积,提高烘干设备的空间利用率,从而有效地提高了烘干效率,降低烘干成本,改善了物料品质;改变了传统管束烘干设备采用一级干燥室的空间利用率低、热能不被充分利用的局面。
The high humidity composite materials for vacuum drying equipment control was developed. Drying mainframe using three different diameter concentric cylinders formed a multi-level drying room. A certain amount of heating control were setted in each dry room, So effectively increased drying efficiency and reduced drying costs and improve quality materials. It can effectively change the situation that the traditional control drying equipment used in a drying room, a low utilization of space, and heat energy equal distribution cannot be fully utilized.
